TO ALL WHOM IT MAY CONCERN: i

Be it known that I, HORATIOYO. PERRY, of the city of Buffalo, in the county of Erie, and Stato of New York, have invented certain new and useful improvements in Machines for Hoisting and Lowering Lading from :and into'the Holds of Vessels; and I hereby declare that the following is a full and exactdcscriptiori thereof, reference being had tothe accompanying drawings, in which Figure is a side elevation.

Figure 2 is a cross-section ot' the shat'ting onV the line B.

Figure is an end elevation of the friction-wheel and brake.

Like letters indicate corresponding parts in all of the tigures.

My invention consists in a line of shafting composed of sections joined together with universal and ext-ensile joints, when employed in combination with suitable appurtenances for hoisting lading from the' holds of vessels orloweriug into the same, said shafting being Varranged ina line ovcr'the deck hatchways, and longi-v tudinally of the i'essel, and connec'ted with and driven byan engine on board the same, theobject of said combination of mechanism being to apply steam power 'tothe elevating and loweringof the freight by means of suitable apparatus driven byund fr'om said lihe of shaftng, the peculiar construction of lwhich, by the, adaptation ot' the jointed sections to the springing or curvature of the vessel under an unequal disposition of her lading, enables such a line ot'shat'ting to be extended from stem to stern, and kept in` motion by the VV engine without `binding and heating of thejournals or other difficulty, which woultlnot be. plossibleqwith a aprilV i tinuous shatt.

My invention is specially designed for use on that class of vessels employed forcarrying freight on lake und shallow waters, denominated |p1'opellcrs, which, to enable them to enter shallow' harbors and rivers, are' v vhuilt'without much depth of hold,'and of great length, in order to give suicient carrying capacity.` In consequence of this construction they are more liable to spring or be deflected from a trueline than vessels of' greater depth of hold; and this deflection occursto the greatest ext-ent while taking and discharging cargo from the irregular disposition of the weightthe'rof before the vessel is trimmed. So great isthe` extent of this deflec-V tion that it is impossible to extend an unbroken line of shafting along the deck of such vessels for the purpose of applying the power of thcpengine to the labor of discharging and taking on cargo, and have the samercmain in working condition, and the demand for performing this labor in the shortest possible-time, so that quick trips may be made, has necessitated my invention, which affords an eieetual remedy.

As represented in the drawings, A A and 'D D are the sections of a line of shaf'ting extended from the vicinity of the engine, which .is usually near-the stern of the boat,'t-o the bow. This shafting is usually hung in brackets' attached to the upper deck over the hatchway; or it may be supported on stanchions M M, or in any other suitable manner. The section A A is provided with a crank for connecting it with'thc engine by means of` a p-itman, so that it may receive 'rotary motion; or it-may'be driven in any other manner. Each section is jointed to the next by -men-ns of the coupling B C, usually called a universal'joint, or by any similar couplingrcapablc of allowingectionfin every direction from a. straight line.v The section A-Ais connected with the part B ofthe coupling, so as to allow it to slide endwise therein, and thus extend or diminish the length of the shafting, according to thc curvature which the vessel may assume. A feather fitted to the shaft, and workingin a. groove in the sleeve, (as vshown in iig. 2,) so connects the sections that they revolirc together as one sha-ft.` The same form of connection is employed in the couplinglat each joint, so that lt-heentire line is capable of ilection und extension or contraction, according to the variations occurring in the form of the vessel.

'.lhis line of'sliaf'ting is employed torrnise and lower through the hatchways tables carrying the lading, which ure connected by ropes, or in any suitable manner, with n. windlass, L, on sha-ft G, which is also provi-ded with a friction-wheel, F, whiclrrcceives its motion by contact with the frietion-pullcyE on the shutting. The axle G has sliding bearings, so that, by means of the lever J J, tig. 3, the wheel `Finay be heldin contact with the driving-pulley E as long as motion is required, and quickly stopped by reversing., thc lever, which removes it from the dri\'i ngpulley,,and holds it against the stationary frictiou-brahercr shoev K,`b.y,which its motion is arrested. l Y v As many of those hoisting machines as there are hatchways, or as are required for otherpurposes, are proL vided, each driven by a friction-pulley on the sha-fting, and each working independently of the others, so that hoisting or lowering may be going un at the differenthntchwnyis, as required, by tokingmotion, when needed,

from the line of shnfting, which revolves steadily and. constantly the meanwhile. flliis line of slxafting may be driven from the main engine, or by a. donkey engi-ne, and not only saves a. large amount of' menual llabor and time, but is applicable to many other useful purposes, such as weighing anchor, and driving bilge or other pumps located at the bow or other part of the vessel, which is eiectefl by suitable connections forA transmitting the motion of the shaft. The last-named use is often of the greatest importance when a vessel trims by the head, or when injured and leaking in the forward portion of the hull.

WhatI claim as my invention, and desire t-o secure by Letters Patent, is-

Forming a. line of shzifting in sections A D, connected by varinble and extensile couplingsv B C, foryuse on ship-board, constructed, arranged, and operating substantially as set foi-th.

I also claim, in combination therewith, the`friction-piilley E, wlieel F, lever J, and 'Drake K, arranged and operating substantially as set forth.

HORATIO 0. PERRY.
